SUBSOIL ATTACHMENT FOR FLOWS.

.SPECIFICATION forming part of Letters Patent No. 680,400, dated August13, 1901.

Application filed June 11,1901.

To all 2071 0111 it may concern:

Be it known that we, JACOB ALEX. SHUPING and CHARLES LUTHER SHUPING,citizens of the United States, residing at Morganton, in the county ofBurke and State of North Carolina, have invented a new and usefulSubsoil Attachment for Plows, of which the following is a specification.

The present invention relates to subsoilplows. The prime object is toprovide a simple and efficient attachment that can be readily andrigidly applied to an ordinary plow,

the only necessary change being the removal of the moldboard andlandside. The necessity of an entirely separate subsoil-plow, with itsconsequent expensiveness, is thus obviated.

In the embodiment shown in the accompanying drawings, the invention isillustrated in connection with a sidehill-plow as now manufactured bythe Lynchburg Plow Company, of Lynchburg, Virginia, under the patentgranted to James R. McWane on February 5, 1901, and numbered 667,558. Itwill of course be understood that it maybe employed upon other plowsand'that such changes may be made from 'the construction shown anddescribed as are within the scope of the appended claims.

In the drawings, Figure 1 is a side elevation showing the improvementapplied to the plow. Fig. 2 is a rear elevation of the same. Fig. 3 is aperspective view of the subsoil attachment detached. Fig. 4 is a detailperspective view of a modified form, illustrating a removable point.Fig. 5 is a cross-sectional view on the line X X of Fig. 4.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings.

The plow illustrated consists of a steelor metallic gooseneck beam 10,having a downwardly-curved end 11, to the rear edge of which is secureda standard 12. The lower edge of this standard has adownwardly-projecting longitudinally-disposed flange 13 and side ribs1%. The construction so far described forms no part of the presentinvention, but is illustrated to more clearly show the application ofthe improvement, which consists of the subsoil attachment, (desig-Serial No. 64,166. (No model.)

nated as a whole by the reference-numeral 15.) This attachment consistsof a shoe 16, at the front portion of which is located the shin 17,disposed at an angle to the shoe and preferably made integral therewith.

The shoe 16 consists of a rectangular bar of metal, provided in itsupper face with a longitudinally-disposed groove 18, that extends fromthe point of connection of the shin to the rear end. A verticalbolt-hole 19 is arranged in the shoe intermediate the ends thereof andopens into the groove. The shin 17 preferably has its rear face curvedto conform to the shape of the portion of the standard against which itabuts, and its front edge is curved and sharpened, as at 20, toconstitute a cutting edge. It is furthermore provided, preferably at itsupper end, with a pair of spaced rearwardly-extending lugs 21, arrangedto embrace the beam, said lugs being provided with alined openings 22,through which a bolt 23 is passed, as is hereinafter more fullyexplained. In the first three figtires of the drawings the nose or point24: of the shoe is made integral with the attachment and has its upperface flattened and inclined toward the lower edge to provide a broadcutting edge 25. In Figs. 4 and 5, however, there is illustrated aslight modification that may be employed, if desired. In the form shownthe nose of the attachment is cut away and a separate point 24; isprovided in its under face with a socket adapted to receive the nose ofthe attachment.

In applying the attachment to the form of plow shown it is onlynecessary to remove the moldboard and landside, whereupon the standardis inserted in the angle formed by the shoe and shin. The bolt 23 isthen passed through the alined openings of the fasteninglugs and througha suitable opening made in the downwardlyextending portion of the beam.In this manner the shin is rigidly attached to the plow. In like mannera bolt is passed through the vertical opening 19, made for that purpose,and also through the usual opening in the lower portion ofthe standard.By this means it will be seen that the attachment can be readily appliedto an ordinary plow, so that it can be employed either for turning or asa subsoiler.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, porportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

1. A subsoil attachment for plows comprising a shoe, a shin located atthe front portion of the shoe and disposed at an angle thereto, andmeans for fastening the shin to the standard of a plow located in theangle formed by the shoe and shin.

2. A subsoil attachment for plows comprising a shoe, a shin locatedatthe front portion of the shoe and disposed at an angle thereto, arearwardly-extending lug located upon the shin, and means for securingthe lug to the standard of a plow located in the angle formed by theshoe and shin.

3. A subsoil attachment for plows comprising a shoe, a shin located atthe front portion of the shoe and disposed at an angle thereto, spacedrearwardly-extending lugs located upon the shin and arranged toembracethe standard of a plow located in the angle forlned'bythe shoeand shin, and means for securing the lugs to said standard.

4. A subsoil attachment for plows comprising a shoe, and a shin locatedat the front portion of the shoe and disposed at an anglev thereto, saidshoe having a groove in its upper face that is arranged to receive thelower end of a standard located in the angle formed by the shoe andshin.

'5. A subsoil attachment. for plows comprising a shoe, a shin located atthe front portion of the shoe and disposed at an angle thereto, saidshoe having a groove in its upper face that is arranged to receivethe.lower end of a standard located in the angle formed by the shoe andshin, and means for fastening said standard in the groove.

6. A subsoil attachment for plows comprising a shoe, a shin located atthe front portion of the shoe and disposed at an angle thereto, saidshoe having a groove in its up per face that is arranged to receive thelower end of a standard located in the angle formed by the shoe andshin, and a bolt passing Vertically through the shoe and arranged toengage the standard to hold it in the groove.

7. A subsoil attachment for plows comprising a shoe, ashin located atthe front portion of the shoe and disposed at an angle thereto, meansfor fastening the shin to the beam of a plow, and means for fasteningthe shoe to the standard of the same.

8. A subsoil attachment for plows comprising a shoe having alongitudinally-disposed groove in its upper face arranged to receive thelower end of a plow-standard, a shin located at the front portion of theshoe and disposed at an angle thereto, said shin having its front endsharpened to constitute a cutting edge, and means for securing theattachment to a plow.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two Witnesses.
